What igniter fits my Tempstar furnace?

The correct replacement for Tempstar model TCK050F12A1 — Silicon Nitride | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Tempstar equipment which lists the model number TCK050F12A1 — Silicon Nitride | Ships Today.

My furnace will not ignite. What part is bad?

A furnace that will not ignite after the draft inducer runs typically has a failed igniter. The hot surface igniter should glow bright orange within 60 seconds. If it does not glow at all, it is cracked or burned out. If it glows weakly, it is degrading and should be replaced preventively. Average lifespan: 3 to 7 years.

Is this igniter compatible with Bryant or Payne systems too?

Many Tempstar parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

Overview

This is the genuine OEM hot surface igniter/sensor (part number 1009524, "IGNITOR/SENSOR HSP SK") for the Tempstar TCK050F12A1 gas furnace. On each call for heat the control board energizes the igniter, which glows red-hot to ignite the gas at the burners. This is a durable silicon-nitride style igniter that resists the cracking and thermal-shock failures common to older silicon-carbide elements. Because the igniter is the most frequently replaced wear part in a modern furnace, a failed unit is the number-one cause of no-heat calls. A cracked or open igniter will not glow, so the gas valve never opens and the furnace locks out — often after several failed ignition attempts and a flashing fault code on the board.

Compatibility

Direct-fit OEM replacement for the Tempstar TCK050F12A1 gas furnace. The same igniter is used across matching ICP, Heil, and Comfortmaker furnaces built on this platform. Verify the connector style and mounting bracket against your existing igniter before installing.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker and shut off the gas, then verify zero voltage with a multimeter.
Access — Remove the burner-compartment service panel to expose the igniter at the burner assembly.
Document — Photograph the igniter position, bracket orientation, and connector routing before disconnecting.
Remove — Unplug the igniter connector and remove the mounting screw(s). Handle the new igniter only by its ceramic base — never touch the silicon-nitride element with bare fingers.
Install — Mount the new igniter so the element sits correctly in the burner flame path, then reconnect the plug per your photo.
Test — Restore gas and power, start a heat cycle, and confirm the igniter glows and the burners light cleanly.

Signs You Need a Replacement
